Apple is holding a media event today at the Yerba Buena Center for the Arts in San Francisco, where it is widely expected to introduce the iPad 3 and an updated Apple TV set-top box. The event is scheduled to kick off at 10:00 AM Pacific Time / 1:00 PM Eastern Time.

Apple will apparently not be providing live video coverage of the event to the public, but a number of news sites will be on hand to provide text and photo updates, and we're including links to several of them here. We will also be updating this article with coverage as the media event unfolds and issuing Twitter updates through our @MacRumorsLive account. Separate news stories regarding the event announcements will go out through our @MacRumors account.

Apple's online stores around the world are currently down in advance of the event.
